Hi Momar33,

I wrote the function espicially for you. It should works. Notice, that you estimate manuaky the maximal number of rows and the maximal number of character in one row.

#include <array.au3>
#include <GUIConstants.au3>

GUICreate(" Centered Inputbox", 200,250)
$cInp = GUICtrlCreateInput ("", 10,  35, 180, 80, BitOr($ES_CENTER, $ES_MULTILINE))  ; will not accept drag&drop files
GUICtrlCreateLabel('Center vertically this text above:', 10, 140, 120, 16)
$cInp1 = GUICtrlCreateInput ("Three or four words", 10,  160, 180, 30, $ES_MULTILINE) 

$btn = GUICtrlCreateButton ("Ok", 40,  195, 60, 20)

GUISetState () 

$msg = 0
While $msg <> $GUI_EVENT_CLOSE
       $msg = GUIGetMsg()
       Select
           Case $msg = $btn
               _CenterV($cInp, GUICtrlRead($cInp1), 5, 29)
       EndSelect
Wend

;                   $sText - text for the inputbox
;                   $iMaxRows - maximal number of the rows in the inputbox
;                   $iMaxStringPerRow - maximal number of characters in one row of the inputboxbox

Func _CenterV($hControl, $sText, $iMaxRows, $iMaxStringLenPerRow)
    Dim $iErr = 0, $sNew ='', $iCounter = 1, $sEmptyRow ='', $sFullRow='', $iEmptyRows= 0

            $sEmptyRow = $sEmptyRow & @CRLF
            $ii =$ii +1

            $sFullRow = $sFullRow &  $avRows[$i]

        Next
            
        $sNew = $sEmptyRow & @CRLF & $sFullRow
        GUICtrlSetData ($cInp, '')  
        GUICtrlSetData ($cInp, $sNew)
    EndIf
    SetError ($iErr, 0, $iErr)
    Return  $sNew
EndFunc
